VK Mail has three main components: an email
daemon that acts as a proxy to any standard mail
server, an email parser, and a Web mailer. All
these together allow users to send email by simply
typing an email address in a standard graphical
Web browser, and allow better anti-spam control
for email recipients. The goal of this project is
not to develop an anti-spam email filter that
simply deletes the junk messages after they are
already delivered to the user. Instead, it
rejects emails from spammers.

The Linux ATA RAID HOWTO explains how to set up RAID 1 (disk mirroring) and then install Red Hat Linux on the mirror device. Promise Technology was one of the first companies to come up with quasi-hardware RAID for inexpensive IDE hard disks. This document covers using the Promise proprietary RAID driver as well as the Linux native ATA RAID.

Sendmail Extended Queue Groups is an m4
file that can be used to add extended queue
groups to Sendmail 8.12.x. Extended queue
groups allow administrators to choose multipe
queue groups based on the sender, recipient,
or sender and recipient pair. This improves
upon the default plain queue groups feature,
which can only operate on recipients.

Angry Sheriff is shell script that runs on UNIX and Linux computers. It downloads and processes realestate foreclosures in NJ (Sheriff's sales in New Jersey). It can be customized to work with any other region if an appropriate Web site (that publishes sheriff's sales legal advts) is known.

Failtence is a text-based password management tool
for Linux. Only hashes of passwords are stored. It
is a single script that is simple and easy to
modify as needed. It uses GPG to save info for
recovery when needed. It encourages the use of
sentences, hints, and passwords. Ideally, one can
write down password hints on pieces of paper
rather than the actual passwords.

Re: Quasi-hardware raid?
SORRY FOR THE TYPO. This is the corrected sentence:

In the case of MD, the boot partition ( /boot or /) must be either simple non-raid partition or mirror partition but not RAID 0, RAID 5, etc.

Re: Quasi-hardware raid?
Correct. There is really no hardware support other than boot-time help from the BIOS on the Promise RAID card (or on-board chip). This is because the card is actually an IDE port extension card with a special BIOS...not really a RAID controller card.

ataraid is new but stable, md raid is not new and proven to be reliable. MD raid has features such as automatic repair (syncing), hot spare partition and ability to function if one of the disks participating in mirror damages. ATARAID currently does not have these features.

On the other hand, ataraid is friendly and seemless with other operating systems. Can co-exist with Windows etc. Also, gives you the ability to share files between operating systems. And because ataraid gets help from BIOS, you can have any type of raid unlike MD. In the case of MD, the boot partition ( /boot or /) must be either simple non-raid partition or mirror partition but not RAID 1, RAID 5, etc.

As ataraid development progresses, hopefully in future benefits of both types of raid will be merged and offered to linux users. If you dont want MD raid features i.e. want something that behaves like hardware raid but you cant afford a hardware raid card, you should use ataraid.
